? Why You Should Plan Ahead for Autumn & Winter Crops

Most gardens start to fade as summer ends — but they don’t have to.

By planning now, you can:

• Extend your harvest beyond the first frosts
• Make the most of empty summer beds after onions, garlic or potatoes
• Improve soil structure with green manures
• Grow more nutrient-dense crops when pests are fewer
• Save money on shop-bought veg over winter

Whether you have a full allotment or just a few containers, there’s still time to sow something valuable now.

? Don’t Forget: Green Manures

If you’re not planting edibles, sow green manure crops to protect and nourish the soil over winter.

Good options include:

• Phacelia – quick-growing and beautiful
• Field beans – fix nitrogen and break up soil
• Mustard – quick cover crop, but avoid in brassica rotations
• Clover – low-growing nitrogen fixer

Cut them down before flowering in spring and dig in to boost soil fertility.

?️ Sowing Tips for Late Summer Success

• Use fresh seed – germination drops quickly in heat or humidity
• Water before and after sowing, especially in dry soil
• Sow in the cool of the evening to reduce stress
• Thin out seedlings early to reduce overcrowding
• Shade or fleece new seedlings during hot spells
• Watch for slugs and snails after rainfall

Containers tip: Use deep pots for roots and leafy greens, and water daily in heat.

? Protecting Crops as Temperatures Drop

As days shorten and nights cool:

• Use cloches, fleece, or cold frames to extend harvests
• Lift containers under cover during frosts
• Mulch around hardy veg like kale and leeks
• Net brassicas against pigeons and cabbage white butterflies

Many leafy greens will slow down but continue growing well into winter with basic protection.
